Sonographic Assessment of Ovarian Follicular Dynamics during Breeding and Non-Breeding Season in Gaddi Goats
...arried out during a full estrous cycle in breeding (B; January-February, n=7) and 21 days in non-breeding (NB; May-June, n=11) seasons. Blood sampling on alternate days was done during both the seasons for serum progesterone (P4) estimations. Follicular growth was characterized by presence of three to five numbers of follicular waves in both seasons. Significantly higher (P<0.01) number of follicular waves (4.0±0.21 versus 3.18±0.12), number o...
